PHP QuickHashIntStringHash::loadFromFilePHP original manual for QuickHashIntStringHash::loadFromFile [ show | php.net ]QuickHashIntStringHash::loadFromFile(PECL quickhash >= Unknown) QuickHashIntStringHash::loadFromFile — This factory method creates a hash from a file Description
public static QuickHashIntStringHash QuickHashIntStringHash::loadFromFile
( string
$filename
[, int $size = 0
[, int $options = 0
]] )This factory method creates a new hash from a definition file on disk. The file format consists of a signature 'QH\0x12\0', the number of elements as a 32 bit signed integer in system Endianness, an unsigned 32 bit integer containing the number of element data to follow in characters. This element data contains all the strings. After the header and the strings, the elements follow in pairs of two unsigned 32 bit integers where the first one is the key, and the second one the index in the element data string. An example could be:
Example #1 QuickHash IntString file format 00000000 51 48 12 00 02 00 00 00 09 00 00 00 4f 4e 45 00 |QH..........ONE.| 00000010 4e 49 4e 45 00 01 00 00 00 00 00 00 00 03 00 00 |NINE............| 00000020 00 04 00 00 00 |.....| 00000025
Example #2 QuickHash IntString file format header signature ('QH'; key type: 1; value type: 2; filler: \0x00) 00000000 51 48 12 00 number of elements: 00000004 02 00 00 00 length of string values (9 characters): 00000008 09 00 00 00 string values: 0000000C 4f 4e 45 00 4e 49 4e 45 00 data string: 00000015 01 00 00 00 00 00 00 00 03 00 00 00 04 00 00 00 key/value 1 (key = 1, string index = 0 ("ONE")): 01 00 00 00 00 00 00 00 key/value 2 (key = 3, string index = 4 ("NINE")): 03 00 00 00 04 00 00 00 Parameters
